I'm back to the game after the recent update. Finished galaxy 1.
It seems fuel scoops / printers / refineries energy efficiency becomes worse as it gets more upgrades. This isn't a big problem for the latter two, but in the galactic stage the fuel scoop gradually loses the ability to sustain itself. I suggest keep its energy efficiency constant to prevent problems.
Another problem is upgrades for the von neumann probes. Upgrading requires retrofitting all the existing probes.
This means: 1. Before entering the accelerated phase, the probes launched by other sectors will require retrofit too, making the retrofit very slow and expensive. I suggest let these other sectors pay for the retrofit of these probes, so the player doesn't have to pay for them.
2. After entering the accelerated phase, if the player has any remaining probes in stock, these will require retrofit and gets really expensive. I suggest adding a way to dispose of them, or simply remove the retrofit requirement at this stage.
